'Not sure if making my wedding cake at midnight the night before my wedding was the best idea,' she captioned the clip.
In Australia, wedding cakes can cost anywhere between $300 to $1200 depending on the number of tiers and details - but Laura's homemade version likely would've cost less than $30.

Since weddings can be outrageously expensive, Laura (pictured) would've saved hundreds of dollars baking the dessert herself - but many described the look as a 'children's birthday cake' or a 'volcano' rather than a dreamy wedding cake
While Laura was happy with the 'cute' end result, others couldn't help but criticise the homemade dessert.
'Is this a joke? Because looks like more for birthday,' one person wrote.
'I can hear your guest judging,' another added, a third said: 'No…just no.'
'Not me thinking you were a professional baker and this was going to turn out so good,' another admitted.
But some praised Laura for giving it a go and saving money baking it herself.
'I think this is the cutest idea!!! Expensive cakes are overrated,' one woman commented.
'Thank god someone has some common sense and doesn't pay $500 for a wedding cake. You're beautiful, let that shine not your cake!' another wrote.
A third said: 'People are so mean. I can't remember anyone's cake at weddings I've been to. If you're happy with it, that's all that matters. It's your day!'
In another video, Laura responded to the haters with images of herself on the wedding day smiling and cutting the cake.
